When veteran centrist Francois Bayrou, France's new prime minister, was education minister in the 1990s, his plan to increase subsidies for private schools led to nationwide protests. He quickly caved in and would stay in the post for four more years.

Three decades later he will face a different force in the shape of a fractured and fractious parliament where one of his earliest tasks — as President Emmanuel Macron's fourth prime minister of the year — will be to pass a budget for 2025.

First he must name a government which, like that of his predecessor Michel Barnier, will have minority support in parliament and be vulnerable to attack from far-right and leftwing opponents.
